Important notes on using KEYLESS-GO
Always carry the KEYLESS-GO card
with you.
Never store the KEYLESS-GO card to-
gether with:
Electronic items such as a cellular
phone or another KEYLESS-GO card
Metallic objects such as coins or
metal foil
Doing so could impair the function of
the KEYLESS-GO system.
Always take a SmartKey with you in
case of a malfunction in the
KEYLESS-GO system.
To lock or unlock the vehicle, the card
must be located outside the vehicle
within approximately 3 ft. (1 m) of a
door or the trunk lid.
In order to start the engine with the
KEYLESS-GO card:
The KEYLESS-GO card must be lo-
cated in the vehicle.
All doors must be closed.
If you have started the engine with the
KEYLESS-GO start/stop button, you
can only turn it off again with this but-
ton, even if you have put the SmartKey
in the starter switch in the meantime.
This does not apply if, after starting, the
selector lever is still in positionP. The
SmartKey will then have priority over
the card and the vehicle’s electrical
system will operate according to the
position of the SmartKey in the starter
switch, even stopping the engine.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take the
KEYLESS-GO card (if so equipped) with you
and lock the vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. Unsupervised use of
vehicle equipment may cause an accident
and/or serious personal injury.!To prevent possible malfunction, avoid
exposing the KEYLESS-GO card to high
levels of electromagnetic radiation.

Easy-entry/exit feature
With the easy-entry/exit feature activated,
the steering wheel tilts upwards and the

turned off.
When the SmartKey is inserted in the start-
er switch or you have pressed the
KEYLESS-GO* start/stop button once and

Effect
P
Park position
Selector position when the vehicle
is parked. Only place selector lever
in positionP when vehicle is
stopped. The park position is not in-
tended to serve as a brake when
the vehicle is parked. Rather, the
driver should always set the park-
ing brake in addition to placing the
selector lever in positionP to se-
cure the vehicle.
The SmartKey can only be removed
from the starter switch with the se-
lector lever in positionP. With the
SmartKey removed, the selector le-
ver is locked in positionP.

R
Reverse gear
Place selector lever in positionR only
when vehicle is stopped.
N
Neutral
No power is transmitted from the en-
gine to the drive axle. When the
brakes are released, the vehicle can
be moved freely (pushed or towed).
To avoid damage to the transmission,
never engageN while driving.
If the ESP is deactivated or malfunc-
tioning:
Only move selector lever toN if the
vehicle is in danger of skidding (e.g.
on icy roads).
D
Drive
The transmission shifts automatical-
ly. All five forward gears are avail-
able.
!Coasting the vehicle, or driving for any
other reason with selector lever inN
can result in transmission damage that
is not covered by the Mercedes-Benz
Limited Warranty.Warning!
G
Getting out of your vehicle with the selector
lever not fully engaged in positionP is dan-
gerous. Also, positionP alone is not intend-
ed to or capable of preventing your vehicle
from moving, possibly hitting people or ob-
jects.
Always set the parking brake in addition to
shifting to positionP (
page 44).
When parked on an incline, turn the front
wheels towards the road curb.
